Good winter propagation continues!

Even though we are well past the shortest day, there is plenty of action inthe mid-afternoons on 6 MHz, 7 MHz, 9 MHz, and 11 MHz.

Good long-haul signals noted on July 14, 2010, in the period 0500 to 0600(3pm to 4pm) - longpath from Europe, Middle East, Africa, shortpath from Asia and Americas.

Here is a sample of spectrum occupancy using the Eton E5, 3 m antenna, atone of my favourite field monitoring sites in the Warrandyte State Park, 20km east of central Melbourne, 25 mins drive from here in Mont Albert!
